Key specs and features:
This size and profile combination allows you to quickly refresh cutting edges while maintaining the factory geometry of your chain.
High Carbon Steel Construction for Long-Lasting Performance
A good sharpening file has to be tougher than the steel it’s cutting. That’s why the ROUND FILES 037103015907 model is built from high carbon steel, a material chosen for hardness, wear resistance, and consistent cutting action.

Benefits of the high carbon steel build:
Durable teeth that stay sharp through repeated sharpening sessions
Clean cutting action that bites into hardened chain teeth without glazing over
Long service life, reducing how often you need to replace your sharpening tools
When you’re maintaining multiple chains over a season, that durability translates to real savings and more uptime in the field.
Knurl-Cut Design for Aggressive Yet Controlled Sharpening
Unlike smooth or standard-cut files, this knurl-cut round chain saw file is engineered to remove metal quickly while still giving you a controlled, predictable feel stroke after stroke. Boulevard Hardware & Supply Co+3Acme Tools+3Golfcrest True Value Hardware+3
What the knurl-cut pattern delivers:
Fast stock removal – fewer passes needed to restore a sharp edge
Efficient chip clearance as the spiral/curved tooth layout helps move filings away from the cutter
Smooth finish that leaves teeth sharp without rough, jagged edges
That balance of bite and smoothness is ideal for everyday chain maintenance where you want sharp cutters without overworking each tooth.
Optimized for Standard Chain Saw Sharpening Technique
Manufacturer and retailer guidance outlines a classic sharpening method using this round file: Summit True Value and NAPA+3DK Hardware+3Liberty Lumber & Metal Supply+3
Tighten chain tension so cutters are firmly supported before filing
File from the inside to the outside of each cutter, maintaining the correct angle (often 20°–45°, depending on chain specs)
Place the file against the beveled cutting surface and use smooth, even strokes
Complete all the cutters on one side (e.g., left-hand cutters), then flip the saw or reposition to work all cutters on the opposite side
This Nicholson round file is sized and shaped to work seamlessly with that standard technique, making it easier to follow chain manufacturer recommendations and maintain consistent tooth profiles.
